 The allure of using (and learning) a programming language is to be able to effectively use it to solve problems, which in and of themselves are simulations of some process we can do in "the real world".
-In this case, we will be writing a program which will implement the mental math techniques for computing the square of any two-digit number that ends with 5.

Do not worry about having to check for invalid or illegal input values (I will not be checking for such when I evaluate your project).

+=====Verification=====
+One of the tests I will perform for output compliance of your code will involve comparing your program's output against a range of input values, to see if they all output in conformance with project specifications.
+I will make use of a checksum to verify exactness.
+You will need to run this from your sof0 project directory with a compiled and operational binary by the name of **sof0**.
+You can check your project by typing in the following at the prompt:
+<cli>
+lab46:~/src/cprog/sof0$ pchk cprog sof0
+</cli>
+If all aligns, you will see this:
+<cli>
+==================================================
+=   CPROG sof0 project output validation tool    =
+==================================================
+sof0 checksum is: 822a47fb2a45845500b6c10878045bd5
+your checksum is: 822a47fb2a45845500b6c10878045bd5
+==================================================
+    verification: SUCCESS!
+==================================================
+</cli>
+If something is off, your checksum will not match the sof0 checksum, and verification will instead say "**MISMATCH**", like follows (note that a mismatched checksum can be anything, and likely not what is seen in this example):

 =====Questions / Food for Thought=====
 These are things I'd like you to contemplate, even use as potential material on your weekly journal entry. The more you think about and understand the problem, the better your ability to solve it and other problems.
